ANNALS COMMENTARY an easy aid to mitigate vertigo I am Professor & Head of the Department of Physiology of a medical college in Dehradun. A few years back, my second daughter was born and it was a difficult pregnancy experience since I had to undergo premature labour due to my problem of 'pregnancy induced hyper-tension'. While I was recovering from my problem, I attended an evening outdoor par...

Understanding the basis of the substrate specificity of cytochrome P450 2B6 (CYP2B6) is important for determining the role of this enzyme in drug metabolism and for predicting new substrates. Pharmacophores were generated for 16 structurally diverse CYP2B6 substrates with Catalyst after overlapping the reaction sites. Two pharmacophores were determined for the CYP2B6 binding site. Both include ...

BACKGROUND/AIM Modulating agents are used to circumvent drug resistance in the clinical setting. However achievable serum concentrations are often lower than those which are optimal in vitro. Combination of modulating agents with non-overlapping toxicities may overcome this obstacle. We have investigated combinations of three modulating agents (quinine, verapamil, and cinnarizine) to circumvent...

OBJECTIVE The aim of the present study is to investigate whether there are geographic differences in the etiology of parkinsonism (PA). BACKGROUND 72% of patients with PA evaluated at movement disorders clinics in the Northern Hemisphere are diagnosed with Parkinson's disease (PD). Data regarding other regions are not available. METHODS We reviewed the charts of all patients with PA seen at...

The growth of new lymphatic vessels (lymphangiogenesis) in tumors is an integral step in the metastatic spread of tumor cells, first to the sentinel lymphnodes that surround the tumor and then elsewhere in the body. Currently, no selective agents designed to prevent lymphatic vessel growth have been approved for clinical use, and there is an important potential clinical niche for antilymphangio...

Melanoma of the uveal tract accounts for approximately 5% of all melanomas and represents the most common primary intraocular malignancy. Despite improvements in diagnosis and more effective local therapies for primary cancer, the rate of metastatic death has not changed in the past forty years. In the present study, we made use of bioinformatics to analyze the data obtained from three public a...

Myocardial cells have two types of Ca channels commonly called T-type and L-type. Whole cell Ca channel currents in guinea pig atrial myocytes can be separated and quantitated by analyzing channel closing kinetics after a brief depolarization (tail current analysis). L-type Ca channels deactivate rapidly when the membrane is repolarized and T-type Ca channels deactivate relatively slowly. Ca ch...
